We are on a mission to back the UKs small businesses by helping them win with a platform that uses clever data to get them funding in minutes, not weeks. We combine the restless energy of a fintech start-up with the stability of a public company, giving our Circlers the autonomy to take ownership and the scale to make a real impact. We are a high-performing team that lifts each other up, challenges each other, and has each others backs. The role is based in London on a hybrid basis, with 2 days in the office. We offer a competitive salary and benefits, including a flexible-first approach, private medical and dental cover, health assessments, a digital GP, life assurance, share schemes, financial coaching, annual learning allowance, electric car and cycle-to-work schemes, season ticket loans, and award-winning parental leave policies. We also provide barista coffee and subsidised Just Eat lunches in our London office, and we have been recognised as one of The Sunday Times Best Companies to Work For 2026.
